Two tiny beads are 25 cm apart with no other charged objects or fields present. bead a has a net charge of magnitude 10 nc and bead b has a net charge of magnitude 1 nc. which one of the following statements is true about the magnitudes of the electric forces on these beads? a. the force on a is 100 times the force on b. b. the force on b is 10 times the force on a. c. the force on b is 100 times the force on a. d. the force on a is 10 times the force on b. e. the force on a is exactly equal to the force on b.

E. The force on A is exactly equal to the force on B.

Explanation:

The force between two charges is given by

where

= Charge on particle 1

= Charge on particle 2

r = Distance between the charges

k = Coulomb constant =

This force will be exerted on both the charges equally.

So, The force on A is exactly equal to the force on B

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
